What type of dampers should be provided at the locations specified in the mechanical code?

The code requires fire/smoke dampers to be installed at specified locations to ensure safety and compliance with building regulations. These dampers play a critical role in controlling the spread of smoke and fire through air ducts and ventilation systems. When a fire occurs, fire/smoke dampers automatically close to prevent flames and toxic smoke from traveling to other areas of the building, thereby protecting occupants and allowing for safer egress routes.

This type of damper is designed with specific materials and functionalities that meet stringent testing and performance standards, such as withstanding high temperatures and maintaining structural integrity during a fire event. By utilizing fire/smoke dampers, a mechanical system adheres to fire safety codes, contributing to overall building safety while protecting both property and life.

Other types of dampers, while useful in various mechanical and industrial applications, do not provide the specific safety functions required by the code in case of fire emergencies.
